.. I was noticing those undrilled bosses on the side of the heads in the pic above and thinking a great time to rig up perfect supports for the plug wires to avoid the headers while the engine is out...

My spark plug wires are in that location, but I'm running fenderwell headers and they work great routed that way.

Ordered Pro-filers today.....195/64 CC, springs for 560
3-4 weeks to get them....
spoke to dave. Super nice guy,took all the time I wanted to chat about the product and my build.
$1050.00 seems like a steal if there as good as I'm hearing.
We shall see sooooon.

.. Kinda surprised you went under 220cc heads with that 248/248 cam and a dual quad TR...

.. Also figured Profiler would have those heads on the truck the next day... looks like a smallish operation...

I spoke to profiler about that, among a couple guys on 1320 tech and was told repeatedly that the 195 "acts" alot bigger then what it is, I likely won't turn the motor more then 6800 and they all seem to think its a good match. I don't have any experience with them so I trusted it. They are small, but very busy, and don't have them sitting on a shelf ready to go. Just the casting, I call, tell them what I want, and they go from there. I also spoke to Chad speires and I can ship them there, spend 500$ for his "econo" port job if I think they heads are holding me back. Or even port them myself if need be. They use the same casting for their 210 heads so there's room to grow if need be.

.. LOL! The guys here tell me that 248/248 cam 'acts' a lot smaller than it is... so should be a good match up..

I'm sensing sarcasm lol......I'm just regurtitating what profiler told me, I called, asked for their recommendation based on the parts I had....this is what the suggested

I would go 210's as well but the 195 are probably the proper head. It will give more snap and power over the entire rpm band. The 210 will give more peak power but over a lesser rpm range. The 195 will give a lot more low end punch in a street driven car. This will make the car faster from point a to point b. Maybe not the best dyno numbers but faster none the less.

That's almost exactly what they said. With this cam and the TR and a self imposed shift point of 6800 I'm not going to be maximizing the airflow of the intake and cam anyways, so they suggested that these heads would likely make less power at the top for a more rounded motor down low. He thinks I will be very surprised at how much torque this will make. And as anyone who follows my occasional drivel on here knows , I love bigger and generally subscribe to more is better theory. It was almost painfull not arguing with the tech guy when I ordered them lol.

.. You may be getting close to maximizing the flow of the Weiand Street TR, since it's ports aren't that big, probably very close to those heads... and smaller ports than the Eddy Street TR uses... guess you can let us know how the ports match up soon...

i was under the impression that this is true. The Edelbrock Street tunnel Ram has larger runners than the Weiand Hi-ram.

I had the Edelbrock tunnel ram. The runners are quite generous.

One day i am going to do another one with a tunnel ram.

Buddy: While the summit cast pistons you are using are very good quality, they are a cast piston. You DO NOT WANT TO experiment with DCR theory and seek maximum compression ratio or the limit on your pump gas with these pistons. You want to stay well within the real world limits of the fuel you are using.
You will make excellent horspower power at a reliable practical 10.5:1cr in your engine.
The real gain of pushing it further is VERY VERY small. You will not go faster. Your luck will run out.
Its just a matter of time.
All you will achieve is busting up a perfectly good set of nice pistons and cylinder walls.

How long do you want to go fast till the luck runs out????

The usual typical failure mod when High speed detonation occurs is a broken top ring land, usually right near the intake valve relief.

A more expensive forged piston just takes longer to fail. If it does not break, it distorts the ring lands and scuff the cylinder walls. The engine if *&^%ed either way. It takes about 5 seconds for this to occur @ WOT and YOU WILL NOT HEAR IT.

On a high performance engine that will see WOT running pay close attention to the recomended top ring end gap.
Especially on a hyper piston. More heat load requires a larger top ring end gap. Horsepower is heat load. more heat more often/less time to remove it.

These pistons are Heat efficient.... translated that means the engine often makes maximum power with a bit less than typical spark advance. KB says about 2 less is typical. It also means the rings gap needs to be generous.

KB's extensive testing has shown clearly that you can and will make equal or more power with a little less engine compression ratio when using a heat efficient piston.
So the need or real payoff to push the cr limit to the absolute max is just not there, when using their pistons.

My KB pistoned 406 is 9.8:1cr. It punches way above it's weight. Stick to a reliable plan and your 355 will too.

I agree, not going to push the envelope......I will stay at 10:5 and be happy I'm sure.

AHHHH !!! Nice, finally a hot rod with the TR setup....im putting together a pile of parts and such for the small block in my 30 Coupe, and after I get it broken in, im planning on that TR being thrown in...HELL YEAH.....nice headers, they Sanderson?
